1. Способ получения бис(4-гидроксиарил)алканов через кислотное каталитическое взаимодействие ароматических гидроксисоединений с кетонами, по которому жидкую фазу содержащую ароматическое гидроксисоединение, кетон и, в данном случае, воду, и газовую фазу, содержащую ароматическое гидроксисоединение, кетон и, в данном случае, воду в такой концентрации, чтобы в реакторе вода из жидкой фазы переходила в газовую фазу, а кетон из газовой фазы переходил в жидкую фазу, пропускают через реактор в противотоке.1. A method for producing bis (4-hydroxyaryl) alkanes through an acid catalytic reaction of aromatic hydroxy compounds with ketones, wherein the liquid phase contains an aromatic hydroxy compound, a ketone and, in this case, water, and a gas phase containing an aromatic hydroxy compound, a ketone and, in this case, the water is in such a concentration that in the reactor the water from the liquid phase passes into the gas phase, and the ketone from the gas phase passes into the liquid phase, pass through the reactor in countercurrent. 2. Способ по п. 1, по которому газовую и жидкую фазу пропускают через реактор в противотоке. 2. The method according to p. 1, in which the gas and liquid phase is passed through the reactor in countercurrent. 3. Способ по п. 1 или 2, по которому концентрация ароматического гидроксисоединения, кетона и, в данном случае, воды, проводимой в реакторе газовой фазы соответствует концентрациям, которые представлены в газовой фазе, и которые находятся в термодинамическом равновесии с проводимой в реакторе жидкой фазой при реакционной температуре и давлении. 3. The method according to p. 1 or 2, in which the concentration of aromatic hydroxy compounds, ketones and, in this case, the water conducted in the gas phase reactor corresponds to the concentrations that are presented in the gas phase, and which are in thermodynamic equilibrium with the liquid carried in the reactor phase at reaction temperature and pressure. 4.

Способ по п. 1 или 2, по которому катализатор используют вместе с сокатализаторами, содержащими серу. 7. The method according to p. 1 or 2, in which the catalyst is used together with cocatalysts containing sulfur. 8. Способ по п. 1 или 2, по которому температура в реакторе выше, чем температура кристаллизации реакционной смеси и составляет максимально 130oС.8. The method according to p. 1 or 2, in which the temperature in the reactor is higher than the crystallization temperature of the reaction mixture and is a maximum of 130 o C. 9. Способ по п. 1 или 2, по которому давление в реакторе составляет 5 - 1000 мбар. 9. The method according to p. 1 or 2, in which the pressure in the reactor is 5 to 1000 mbar. 10. Способ по п. 1 или 2, по которому ароматическим гидроксисоединением является фенол. 10. The method according to p. 1 or 2, in which the aromatic hydroxy compound is phenol. 11. Способ по п. 1 или 2, по которому кетоном является ацетон. 11. The method according to p. 1 or 2, in which the ketone is acetone. 12. Способ по п. 1 или 2, по которому в качестве реактора используют ректификационную колонну. 12. The method according to p. 1 or 2, in which a distillation column is used as a reactor. 13. Способ по п. 1 или 2, по которому проводимая в реакторе жидкая фаза содержит ароматическое гидроксисоединение, кетон и образованный из них реакционный продукт. 13. The method according to p. 1 or 2, in which the liquid phase carried out in the reactor contains an aromatic hydroxy compound, a ketone and a reaction product formed from them.
